Versatility of StackReg syntax in FIJI / ImageJ

Dear all,
I first did a macro in ImageJ 1.52s and inside I call the stackreg :
run("StackReg ", “transformation=Translation”);
When I wanted to run the same macro in Fiji (IJ1.52s) the command was not recognized. So I recorded the command in Fiji and got :
run(“StackReg”, “transformation=Translation”);
This problem is only due to a space between the “g” and the coma… Does anybody knows a way to avoid this problem?
Thanks in advance,
Best regards,
Frédéric
